Interestingly, in the original Out of the Pit, Crocodiles are only noted as inhabiting Rivers, Lakes, and Sea, and also appear on the Encounter Table for Rivers/Lakes.[3] They are nowhere to be seen for what you would think would be their ideal habitat - Marshes. Having said that, later works do note the: "steamy, crocodile-infested swamplands of southern Allansia".[4]

There would appear to be many different kinds of Crocodile spread across Titan. Bear in mind that all of the following are based on extrapolations of the books that they occur in.[5] In Allansia for example, we have the:

There are absolutely no references in canon to Crocodiles in the Old World, and thus probably no Crocodiles living on that continent, but nearby, on the islands that dot the Western Ocean, we find the:

Crocodiles are huge reptiles, often as much as six metres long.[1] They have four legs with webbed feet, a vertically-flattened tail for propelling them through the water, and long, tooth-filled jaws for catching prey. Crocodiles are covered in armoured scales that range in colour from yellow through green and grey, to almost black.

Crocodiles are not so skilled when fighting on land (their skill being reduced by 2 points), but if they can lure or drag their prey into the water to fight, they will prove deadly opponents.[1]

This is represented by making an opponent fighting a Crocodile reduce their Attack Strength by 1 whilst standing waist-deep in water.[6] Alternatively, there are a range of skill modifiers for combat depending on whether the victim is knee-deep in water (-2), waist-deep (-4), up to their neck (-6), or swimming (-8).[7]

Crocodiles are known for their voracious appetites, and they spend much of their day swimming in search of fish, or larger prey if they are lucky, visible only as a pair of eyes peeking out above the surface of the water. The rest of the time they will be basking on the shore in the sun. Crocodiles may be tremendously aggressive, and are not afraid to attack men or other creatures which disturb them.[1]

An excellent away to avoid the attack of a Crocodile is to thrust an iron bar between its jaws as it attacks. This wedges its jaws open and renders it helpless.[8]

Two Orcs were sitting beside a river when one let out a sudden yell.'Whassamatter?' the other demanded.'Blinkin' crocodile just bit off me foot,' came the reply.'Which one?'The other Orc looked puzzled. 'Who cares? Them crocs all look the same to me.'[16]
